"After the Catch": Go behind the scenes of "Deadliest Catch" to get the lowdown on the crab fishermen who brave the elements to do their jobs. Mike Rowe hosts, and the crew gathers in Breckinridge, Colo., to raise a cool one at a watering hole called the Whale's Tail. (Isn't Colorado landlocked? Oh, well). (10 p.m., Discovery)
